Llanerch Hall, Trefnant, Clwyd, Wales, is a country house with medieval origins. It was rebuilt twice at the beginning and at the end of the 17th century, was again rebuilt in the 19th century, and further modified in the 20th. The hall is now divided into flats, each with its own Grade II* listing. The parkland, now a golf course, conceals traces of a late 17th century Italianate terraced garden that rivalled those at Powis Castle. The gardens were entirely destroyed in the 19th century rebuilding. The house remains privately owned.
